Modern society is filled with the pursuit of material wealth and great convenience due to high technology that has been introduced to all facets of society. There is no exception to this in the field of construction. Modern construction, however, has caused environmental destruction and pollution, disturbing the coexistence of humans and nature. Therefore, this thesis aims to explore how humans and nature can maintain a mutually beneficial relationship by looking into the construction of Jeju's traditional dwelling house. This thesis examines the geographical features of Jeju and looks into how Jeju people have adapted themselves to nature. It is assumed that geographical features have created Jeju's unique environment and style of architecture and differentiated Jeju's traditional houses from those of other regions. Also, it is considered that geographical features had a large impact on traditional construction such as the floor plan and the layout of buildings. Accordingly, this thesis explores the way traditional houses protected house dwellers from the natural environment and examines the wisdom of our ancestors who took advantage of the natural environment. In addition, this thesis aims to contribute to creating Jeju's unique construction culture and environment by studying materials, structures, and forms that were applied to the traditional houses of Jeju.

Today, each country's cultural communications are carried briskly and Japan already showed a new trend of world fashion by accepting its own design with aesthetic sense to western Europe in 1970s and built the new area of Japanese fashion. This special traditional aesthetic sense, formed by social, cultural, geographic and religious conditions, is roughly divided into decorated and undecorated beauty; decorated one means splendidness, coquetry, exaggeration and was represented ornamental modification of nature object in dress pattern as ornamental expression means; undecorated one, based on Zen-thought, means simplicity, purity, ugliness and Japan gave rise to the new beauty by receiving and adapting continental culture to its culture openly and creating and developing its own beauty. This study aims to examine the aesthetic sense shown in Japanese traditional dress and understand how traditional beauty is used and applied to modern fashion and analyze the diversity of Japanese traditional aesthetic sense shown in modern fashion. For material analysis, total 220 were collected of photograph related to formative element existence according to aesthetic sense shown in Japanese traditional fashion design using literature research and visual data. The existences of Japanese image among them were confirmed by clothing and fashion department majors so that 7 pieces of which were selected as final analysis object. Likewise, the result suggests that Japanese traditional aesthetic sense creates global design based on folk element-used identity as well as new beauty by adapting continental culture to its culture openly and producing and developing its own creative beauty.

새로운 문화 시대의 대두와 동아시아의 문화적 역할 증대는 한국 문화의 위상과 정체성 확립을 필요로 하게 되었다. 이에 본 연구는 조형의 기본인 의장, 특히 형태 조성의 근본이 되는 재료를 중심으로 실제 조사를 통해 유사한 한 중 일 삼국의 건축재료 중에서 한국재료의 특성을 파악하고자 한다. 연구는 문헌 조사와 현지 답사를 함께 진행하였으며 조사의 대상이 된 한 중 일의 궁궐은 창덕궁, 자금성, 니조성이다. 한국의 재료는 목재, 석재, 토재, 금속재, 초재 등의 자연 재료를 사용한다는 한 중 일 공통적 특성과 함께 재료에 있어 자연적 가공도가 높고 대체적으로 거친 질감을 그대로 살리고 있다. 이에 비해 중국의 재료는 인위적 가공도가 높고, 표면 질감이 매끈하다. 한편 일본은 재료의 인위적 가공도가 높으나 질감면에서는 자연스러운 거친 질감을 즐겨 재료의 질감표현을 위해 오히려 인위적인 가공을 더하는 경향을 나타내고 있다. 한 중 일 삼국에 나타난 재료 특성은 우선 한국의 재료는 가장 자연적이고 중국의 재료는 가장 인위적이다. 이에 비해 일본의 재료는 한국과 중국 두 나라의 재료 특성을 모두 지니고 있는데, 가공도가 높을수록 재료 표면이 거칠어지고 있다 이는 선행된 연구에서 당연하게 여겨졌던 한국 문화의 위치 즉, 중국과 일본의 중간적 성격을 띠고 있다는 것과는 대치되는 것으로서 이전의 연구가 선을 중심으로 한 형태 위주의 연구가 많았기에 파악되지 않았던 특색으로 보인다. 또한 재료의 가공은 자연적 영향보다는 그를 기반으로 하는 각 민족의 의식과 창의성의 발현으로 파악되는데, 특히 한 중 일 삼국의 자연 친화 사상의 표현 방식에 연유하는 바가 크다고 사료된다.

The Hwangtoh is one of the traditional construction material used in wall, plastering material, and ondol (Korean underfloor heating system) with stone and wood. It is an important greenness material and it has much advantages such as; high storage of heat, auto-purification, antibiotic ability, and emission of far infrared rays. But, it is not developed and not used in modern construction because of its low strength and properties of dry shrinkage crack. According to the recent researches and studies, it is evaluated for natural pozzolanic material like flyash or pozzolan. It's possibility on construction material is high because it's chemical and mineralogical proportion is like as Metakaolin and Kaolinite. In this point of view, this study aims to analyze the physical properties on Hwangtoh mortar through an experiment with various activation condition of Hwangtoh, which is natural pozzolanic material, for the purpose of increase the using possibility in construction material.

이 연구에서는 무령왕릉에 사용된 전돌의 재료 특성에 관하여 고찰하였다. 압축 강도, 열전도도, 흡수율 등의 재료 특성은 비파괴 실험으로 측정하였다. 그 중에서 무령왕릉 전돌의 압축강도는 초음파 측정법과 흡수율을 이용하여 추정하였다. 실험 결과, 초음파 속도를 이용한 압축강도는 표면이 고르지 못하고 두께 편차가 큰 문화재 시편 특성상 표준편차가 크게 나타났다. 그러나 흡수율을 적용한 압축강도 값 (28.69 MPa ~ 33.19 MPa)은 일반 콘크리트의 압축강도 수준으로 편차가 낮게 나타났다. 따라서 초음파 속도를 이용하는 방법보다 흡수율을 이용하는 방법이 무령왕릉 전돌의 압축강도 예측법으로 보다 적합한 것으로 판단된다. 무령왕릉 전돌의 열전도도는 시료의 표면상태와 두께에 영향을 받지 않는 Mathis TCi를 이용하여 측정하였으며, 평균 1.58 W/mK로 흙에 근접한 값을 지닌다. 무령왕릉 전돌의 흡수율과 수분 잔류율은 각각 1.6 % ~ 15 %, 0 % ~ 0.7 %의 범위를 나타냈다.

In this study, a total of 58 different kinds of nuruk (a traditional Korean fermentation starter) were prepared, including 46 kinds of restored nuruk from ancient documents. Each nuruk was evaluated by analysis of its saccharification power, and the enzyme activities of glucoamylase, ${\alpha}$-amylase, ${\beta}$-amylase, protease, and ${\beta}$-glucanase. The range of saccharification power (sp) of the restored nuruk ranged between 85 and 565 sp. The diastatic enzymes, ${\alpha}$-amylase, ${\beta}$-amylase, and glucoamylase, were significantly correlated to the saccharification power value; conversely, ${\beta}$-glucanase and protease did not have a correlative relationship with saccarification power. In addition, their brewing properties on chemical and organoleptic aspects of traditional alcoholic beverage production were compared. Each raw and supplementary material contained in nuruk showed its own unique characteristics on Korean alcoholic beverage brewing. For the first time, in this study, the traditional Korean nuruk types mentioned in ancient documents were restored using modernized production methods, and also characterized based on their brewing properties. Our results could be utilized as a basis for further study of traditional alcoholic beverages and their valuable microorganisms.

This study aims to develop fashion designs that combine atlas fabric with the characteristics of Uygur costume to modernize the costume of the Xinjiang Uygur. Research contents and methods are as follows. First, based on previous studies, research analysis was conducted on the cultural background, clothing characteristics, and material of Uygur clothing. Second, based on such research contents, designs combining the characteristics of Uygur costume and atlas fabric were presented. Third, to analyze the utilization of atlas fabric and examine fabric characteristics, material was gathered from collections on domestic and foreign web sites. Through field explorations of local museums in the Xinjiang area, minority group culture was observed in more detail. Based on collection of traditional clothing and analysis of its characteristics, fashion designs that apply contemporary trends were developed. General silhouettes without any restrictions to the waist and decorations made using embroidery were often used. Atlas silk, developed in China using Ikat weaving methods, is an important traditional clothing fabric of the minority group Xinjiang. Based on such data collection analysis, the produced works highlighted traditional ethnic characteristics by extracting classical patterns of atlas fabric, modifying or partially expanding them, combining them with hand knitting, and adding contemporary sensations, thus providing confirmations of the possibility of popularizing classic patterns in more practical manners.

This study progressed an investigation on the cause of the efflorescence phenomenon of bricks in Suwon Hwaseong Fortress, which is designated as a UNESCO World Heritage by using diverse scientific analyses. The samples were taken in Hwaseong and analyzed using XRD and SEM-EDS for the material identification of efflorescence. We observed under a polarizing microscope and measured absorption factors for the basic investigation for traditional bricks. As a result of material identification, soluble salt($Na_2SO_4$, $KNO_3$) and insoluble salt($CaCO_3$) were detected. There was no big difference between original bricks and repaired bricks under the polarizing microscope. However, in terms of the water absorption rate, bricks which were used for repair nowadays showed low water absorption rate(1%). In conclusion, soluble salt and insoluble salt appeared due to an effect of an air pollution and joint mortar. Soluble salt was removed in the rainy season, but insoluble salt was not removed. As a result of the efficiency and safety tests for chemicals removing efflorescence, chemical E is likely to be the suitable chemicals for the efflorescence phenomenon of traditional bricks in Suwon Hwaseong Fortress. In the future, consideration whether the use of lime is available or not should be studied through comprehensive researches including repair work, construction work and the environment factor with lime. Also, physical, chemical identifications of repairing bricks will be required.

The main purpose of this study is to analyze the effects of external pressure on the vibration and buckling of functionally graded (FG) spherical panels resting of elastic medium. The material characteristics of the FG sphere continuously vary through the thickness direction based on the power-law rule. In accordance with first-order shear deformation shell theory and by the use of Ritz formulation the governing equations are presented. In this regard, the beam functions are applied in two-dimensions for different sets of boundary supports. The Winkler and Pasternak models of elastic foundations are also taken into account. In order to show the validity and applicability of the presented formulation, various comparison studies are given. Furthermore, a diverse range of numerical results is reported to check the impacts of geometrical and material parameters along with external pressure on the vibration and buckling analysis of FG spherical panels.

This paper investigates the limits and efficacies of the Fiber Reinforced Polymer (FRP) material for strengthening mid-rise RC buildings against seismic actions. Turkey, the region of the highest seismic risk in Europe, is chosen as the case-study country, the building stock of which consists in its vast majority of mid-rise RC residential and/or commercial buildings. Strengthening with traditional methods is usually applied in most projects, as ordinary construction materials and no specialized workmanship are required. However, in cases of tight time constraints, architectural limitations, durability issues or higher demand for ductile performance, FRP material is often opted for since the most recent Turkish Earthquake Code allows engineers to employ this advanced-technology product to overcome issues of inadequate ductility or shear capacity of existing RC buildings. The paper compares strengthening of a characteristically typical mid-rise Turkish RC building by two methods, i.e., traditional column jacketing and FRP strengthening, evaluating their effectiveness with respect to the requirements of the Turkish Earthquake Code. The effect of FRP confinement is explicitly taken into account in the numerical model, unlike the common procedure followed according to which the demand on un-strengthened members is established and then mere section analyses are employed to meet the additional demands.
